SUPPORT.

Application ied 'March 22, .1924. Serial' No. 7003984.-

This invention relates to supports by which pipes, cables', sha'iting, etc., are attached to the ceilings, walls and the like, of buildings, or other structures. Hei'etoiiore, supports of this character have included oints or connec# tions that either limited the use of the sup#l ports or were unreliable vin service because they loosened under the action ot vibrations. lt is, therefore, the principal object oi'v this invention to provide al support suitedl toa Wide range of Work andI one which -Will securely hold pipes or brackets carrying them in spite oit vibrations or casual movements of' any kind.

Further objects 'of the invention are to provide a support includingan insert adapted to be easily attached to concrete forms, setvbe tween brick orfstone during construction, or lined in pockets cut in existing structures, and a simpley anchorageelement that Will` quickly and securely fasten a bolt, or the like, tothe insert after the-latter has been implaced; and to pro 'ide a constructionthat can be manufactured and used by unskilledl la"boi','the're-` by effecting' economy both iirmanufacture and installation. l Further obJects andadvantages of fthe'in# vention will become apparent as the disclosure proceeds and the description'is read in connection with the accompanying, drawings il'- lustrating a selected'embodiinent of theinvention, and in which 1 shows the insert nailed to the concrete liorin'work and embedded in theconcrete;

F 2 shows the insert after the form Work has been removed and a bolt` has been secured therein by means of theanchorageelement;

l Fig. 8 is a sectional-view takenfon the line 3430i Fig, and

Fig. 4 is a view illustrating the operationl ot setting` the anchorage element in the socketV of the insert.

rlhe support includesan insert generally indicated by the' reference numeral 10 in which an anchorage element 11 secures a bolt, Y

or the like, 12. The insert in the preferred forni here illustrated, includes a bottom ory base 13 above which is a socket portion 14 that is connected by stout legs 15 with a plate or anchor 16. The plate 16 is of suitable form the building; material, andthe passagel? between the legs permits the building material to pass entirely under the plate and form a solid connection. A Vconvenient torni is that tangular in cross section so as to cooperate With thepolygonal head 20 of thebolt 12 in a Well yunderstood manner, butfwhere more convenientv the cavitymay take adilferent form;` It is not necessary that the cavity. be such asfto fit ytl'iehead-ot` 'the bolt or other fastening-tightly, and it is contemplated that inserts oi one sizeinay be used in connection With'bolts of different sizes but having heads too'la-rge to rotate'morethan part of -aturn Within'thecavity; I Y

The'preferred anchorageelement 11, here illustrated, is substantially inverted U-shaped in form prior to'iassembly, as indicated in Figi/l.: It may bemade'troin -bar stockoi` suitable strengthv by bending." into the 'shape shown; in Figyl, and yperforatinp; the upper or crosspai'tbetween the legs of' the U. Then the pipes, or the like,l are .to` be installed,

suitable'l bolts are passed through the anchois 'age elements and the assen'iblies'thus made ai'e entered intothefsockets of the'inserts, as shownin F 4, and afterwards theianchor age elements are' spread or` expanded as illustrated inid'otted lines in that ligure, to place the lower ends of the legs of the U' in engagement With suitableseats inthe'sockets. 'InA this' preferred .construction tivo et the Walls 21 and 22 of the socket are set back, as illustratc'd 1, 2 and 2 1-, to expose seats 23 on the upper si de of the base 13.1 Better support Will'b'ehad if the'iieet 24 ot-the'leg's are slightly beveled soas to litf evenly along` the seats Q3. l A

The assembly will be tacilitatedby the use of a tool illustrated in Fig'. Il. which mav take the form of a rectangular piece oi tubine' having' its end Walls 26 on opposite sides tairand dimensions to provide a strong grip on tered. and the intermediate end Walls 27 beveled to effect the spreading' or opening of the anchorage elements, as Will be clear from Fig. 4.

. It is contemplated that the invention Will. y

find its principal use in connection with concrete structures. The inserts will be nailed to the forni work of the floors or the colui'nns, or the like, before the concrete is iun in. After the concrete is set the Joriiis will be wrecked and the inserts will be cast solidly in the concrete with the bases 13 exposed and presenting the openings 28 by which the bolts and anchorage eleinents are entered. l/Vhen the pipes, or the like, are to be installed, suitable bolts and anchorage elements are entered into the sockets by the aid of the tool 25, and a haininer or inallet, if necessary, and the anchorage elenients are opened or spread to set the feet iirinly on the seats 23.

With this invention a bolt, or several bolts, niay be securely connected to the concrete, or the building niaterial and any suitablehanger or bracket niay be securely mounted inY place with a niiiiiniuin of ei'lbit. When once set in place there is no likelihood loosening because the load, whether suspended from the ceiling or supported on the side of a col-v unin, will tend to prevent disconnection of the bolt 'from the insert rather than perinit the anchorage element to be released.

I ain aware that the insert may be varied in il'iorni to suit different uses and the anchorage eleinent may be einebodied in different shapes and constructions and l do not wish to be liniited except as is iiiade necessary by the prior art.

I claini as niy invention 1. In a device of the class described, the combination of an insert adapted to be set into a structure so as to have one 'face exposed and including a socket accessible through an opening in the exposed face, seats in the socket adjacent to the opening` a bolt having` a head located in the socket and a per-v v foratcd anchorage eleincnt receiving said bolt and having downwardly and outwardly eX- tendod legs resting on said seats, said anchorage element beingv separate 'from the insert and having been introduced through the opening and spread to rest the legs upon the seats and thereby prevent withdrawal of the bolt.

2. In a device oi the class described, the

combination of an insert adapted to be set into a structure so as to have one aee exposed and including` a socket accessible through an opening in the exposed face, a seat adiacent arched anchorage c-leincnt inserted through the opening and so spread as to rest on said seats.

4. In a device of the class described, the

combination of an insert adapted to be set into a structure so as to have one tace exposed and including a socket accessible through an opening in the exposed face, seats on opposite sides of the opening and an anchorage elenicnt inserted through the opening and having bendable legs spread to straddle the opening and rest on sai(L seats.

5. InV a'device oit the class described, the combination of an insert adapted to be set into structure so as to have one face ei(- posed and including a socket accessible through an opening in the exposed tard-seats' on opposite sides oit choiage eleuient comprising a perforated bar arched upwardly and having its endsresting on said seats.y

6, ln a device oit the class described, an insert adapted to be set into a structure and including a perforated base and a'hollow socket portion extending upwardly trein the base, the hollow being` oft a sii/ie and shape to receive a bolt head andkprevent it rotating, an upwardly arched anchorage element inserted through the perforated base and siliread to'straddle the,perforation and rest on the base at opposite sides ot the peritoration.

7. In a device ot the class deserib'ei'l` an insert adapted to be set in a structure and in-` cluding a socket accessible through an opening in one face th ereof, seats on opposite sides ot said openings and an anchorage elenieiit ccniprising a U-sliaped bar perforated inter inediately toreceive a bolt and adapted to be spread to rest its ends on'saifd seats.
